There is a lot that you can do for your gums yourself, but it is always advisable to go to a dentist for such a problem, particularly if it lasts longer than two days or if it occurs often. If you are suffering from gingivitis and it remains untreated for a long time, it could become a more serious infection and could eventually result in a loss of teeth.
If it is not too painful, you should massage your gums gently a couple of times a day; this will improve circulation and ease the pain to some extent. Brushing your teeth is something you should not skip, even if you are tempted to do so because of the pain. Brush your teeth gently but thoroughly, taking at least three minutes to do it, and make sure that the brushing action covers your gums as well. After brushing your teeth and gums, you should also brush your tongue to get rid of any bacteria that might have lodged themselves there. You should floss your teeth as well, and after brushing and flossing, use a mouthwash to rinse your mouth thoroughly. Mouthwash can be used several times through the day, but you can rinse your mouth with warm salt water instead.
